You are too young for the adult moove, to avoid pregnancy
you should avoid the idea of sex itelf, your mother also do not want you to have this fot the same reason.
At this age you should devote time for you studies rather.
Condoms if used with caution is reasonably safe contaceptive and it also protects you from sexually transmitted diseases. Other options are copper-T, oral contraceptives-the pill.
But they are hardly practical for you.
If you have any further query please let me know I would try to answer it for you.
Wish you a great health!
